基于智能拟合法的气液相平衡预测

利用自行开发的智能拟合法对甲醇—水溶液气液相平衡数据进行拟合,得到该溶液气液相平衡的最佳预测式及其预测结果,并将预测结果与传统预测式的预测结果进行了对比。结果表明,智能拟合法可以自动搜索得到最佳拟合式,具有形式简单、预测精度高的优点。该方法不仅对甲醇—水溶液适用,而且对其它平衡曲线无下凹的中等非理想溶液的气液相平衡预测均适用,具有广阔的应用前景。

Prediction Based on Intelligence Phase Equilibrium Fitting

The balancing data of the methanol solution is fitted,through making use of the intelligent fitting method that is developed by ourselves,and the optimum forecast equation and its forecast result is getted,compare this forecast result with the forecast result of the traditional forecast equation.The results show that the intelligent fitting method can automatically search for the optimum fitting equation.Its form is simple and the forecast precision is exact.The intelligent fitting method is a general method.It adapts to not only the balancing forecast of the methanol solution but also the balancing forecast of other moderate unfavorable solution that its balancing curve isn’t concave.It possesses wide applied prospect.
